Air Dispersed Applicators
ELECTROMATIC XIX Automatic Applicator
The air dispersed method of applying hot melt adhesive consists of
extruding a solid stream of material into impinging air patterns. The
impinging air patterns cause the material to "rotate" with a
spiraling effect with the end result being interlocking, circular type
patterns being applied. The width of the pattern, typically ½" to
1" wide, is controlled by a combination of fluid and air pressure, as
well as distance of the applicator from the substrate. When patterns beyond
1" wide are designed, multiple applicator heads will be required if a
clean edge is required.
ELECTROMATIC XII Handgun Applicator
Such guns are designed to apply a "filament type cone shaped, spray
pattern" (refer to sketch of typical pattern shown on literature SL318)
which will usually range from ¼" to 1" wide, with the actual width
obtained dependent on a number of variables including characteristics of
actual material dispensed, application temperatures, heated air supply
temperatures, distance from and actual speed of substrate, operating fluid
and air dispersing pressures, etc., and it is difficult, if not impossible,
to accurately determine the pattern capabilities of the gun without running
The majority of applications, particularly where close control
of the applied pattern is desired, will also require a supply of heated air
for "dispersing" purposes which can be accomplished by utilizing a
Heated Air Supply Unit which generally is suitable for the operation of up to
two ELECTROMATIC Air Dispersed Applicator
Heads. It is possible to dispense a "sprayed" pattern using
"cold" dispersing air, but a marked improvement will be evident if
a heated air supply is used.
Standard models are supplied with a "universal" fluid tip and
air cap, which has been proven to be suitable for the majority of
applications. However, when required, modifications can be made to such
components resulting in different patterns. Multiple outlet applicator heads
are available to apply wider patterns, such as might be required in various
disposable applications. Multiple outlet applicator heads will be quoted upon
receipt of all application requirements. All models are fitted with heaters
and RTD temperature sensors, which are compatible with standard SPRAYMATION THERMOPULSE Hot Melt Systems and/or gun conversion
kits, with electrical connections made via an included electrical socket.
It is important to note that pattern variations may occur based on the
material being used, and that the only way to satisfactorily determine
equipment, application and material compatibility is through testing with
experimentation carried out as to fluid and air pressures and temperatures.
